• TLF-IDL1076

Explore ways of representing decimals using mathematical notation and visual tools. Match a decimal fraction between 0 and 1 such as 0.7. Adjust units on an area representation and a common fraction. Match three decimals with each tool.

• TLF-IDA004929

In this lesson, students learn about place value and how it extends beyond whole numbers. They use decimal notation to name and represent decimals and use materials to model decimals. These models help students to order and compare decimals that include tenths, hundredths and thousandths.

• TLF-IDA004299

The focus of this activity is to find out what students know about addition of decimals and what are some of the different strategies students are able to use and explain. Do students prefer to use equations or do students rely more on empty number lines?

• TLF-IDA004330

This activity allows students to develop an understanding of decimals and how they connect to fractions and the area model. It enables them to make comparisons between decimals and their sizes and build a greater understanding of what makes a larger decimal and smaller decimal. The decimats provide them with a representational ...

• TLF-IDA003329

Use this video to explore decimal fractions, how they are represented and how we use them in day-to-day contexts.

• TLF-IDM021836

This lesson engages students in investigating place value by considering a counting system using base 8. Students are challenged to imagine how place value would work in a cartoon world where everyone only had eight fingers. They engage in activities with counting blocks, representing numbers in base 10 and in base 8 and ...
